[SPDK] QEMU virtio-scs and options

Hello!

 In the example page (at https://spdk.io/doc/vhost.html#vhost_qemu_config ) I see:

-chardev socket,id=spdk_vhost_scsi0,path=/var/tmp/vhost.0 \
-device vhost-user-scsi-pci,id=scsi0,chardev=spdk_vhost_scsi0,num_queues=2

QEMU-KVM return error:
2021-09-05T09:33:28.912405Z qemu-kvm: -device vhost-user-scsi-pci,id=scsi0,chardev=spdk_vhost_scsi0,num_queues=2: 'vhost-user-scsi-pci' is not a valid device model name

I changed vhost-user-scsi-pci to virtio-scsi-pci . Got:

2021-09-05T09:36:05.963504Z qemu-kvm: -device virtio-scsi-pci,id=scsi0,chardev=spdk_vhost_scsi0,num_queues=2: Property '.chardev' not found

So, can someone help me with a right options ?

TIA.
